Determine whether the objects in the following problems have kinetic energy (KE) or potential energy (PE). Then, use the appropriate formula to calculate the answer.

You serve a volleyball with a mass of 2 kg. The ball leaves your hand with a speed of 30 m/s. The ball has kinetic energy. Calculate it.

A baby carriage is sitting at the top of a hill that is 20 m high. The carriage with the baby in it weighs 10 kg. The carriage has potential energy. Calculate it.

A car is traveling with a velocity of 20 m/s and has a weight (mass) of 1000 kg. The car has kinetic energy. Calculate it.

There is a bell at the top of a tower that is 20 m high. The bell weighs 100 kg. The bell has potential energy. Calculate it.
KE = (0.5)(m)(v)2

Here are the formulas:

m = mass (in kg

v = velocity (in m/s)

PE = mx g x h

m = mass (in kg

On Earth, gravity, g = 9.8 m/s2

h = height (in m)

Answers

Answer: The energy of the ball is 945 Joule

Explanation: A volleyball with a mass of leaves the hand with a speed of .

To find:

The total energy of the ball.

Consider that the ball exists moving very close to the ground. Hence its potential energy should be zero.

If the ball will possess kinetic energy by the virtue of its motion.

So, net energy or kinetic energy:

Kinetic energy

Therefore, the energy of the ball is 945 Joule.

What is a scientific theory is and under what conditions a theory may be revised?

A theory does not explain but it states the relationships between variables. It can be revised at any time if someone disagrees with it.
A theory is an explanation for a scientific phenomenon. It answers WHY and HOW type questions about the natural world. A theory is based on extensive testing and experimentation and is taken as truth. Sometimes, however, a theory must be revised. This happens when new knowledge or new technology expands and corrects our understanding.
A theory is only a guess and can be revised by anyone.

1.
Maximum kinetic energy

2.
Potential and kinetic energy is equal

3.
Maximum potential energy

Answers

Q1) Answer:
The average speed of the blocks are 0.36 m/S.
Explanation:
Average speed is defined as the ratio of distance covered per unit time. So if it is said that blocks are pulled to 0.9 m in the right side. This means the blocks cover a distance of 0.9 m from the origin and that distance is covered in 2.5 s. Thus, the average speed can be calculated from the change in speed
with respect to time. As at time t = 0, the speed is
also zero, and at time t = 2.5 s, the speed will be
Speed =
0.9 = 0.36
2.5
Since, in this case, the speed is equal to the average speed of blocks. So the average speed of the blocks will be 0.36 m/s.

Which of the following forces has not changed Earth's surface?

folding
erosion
weathering
gravity

Answers

Answer:Gravity is the force among the options listed that has not directly changed Earth's surface.

Explanation:

Gravity is a fundamental force that acts on all objects with mass, including the Earth itself, but it does not cause changes or modifications to the Earth's surface features. Instead, gravity influences the movement of materials and the shape of the Earth's surface by exerting a pulling force on objects. On the other hand, folding, erosion, and weathering are all processes that directly contribute to shaping

The waves have energy that wave back and forth because the waves are never still, they are always moving. There are different types of waves because sometimes (like a tsunami) the waves are affected by other things like the earth plates.

Do nutrients cause seagrass to grow more in this area? If so, are both nitrogen and phosphorus equally important? Explain your answer.

Answers

Seagrasses are a vital part of the marine ecosystem..

Seagrasses are submerged flowering plants found in shallow marine waters, such as bays and lagoons and along the continental shelf in the Gulf of Mexico. A vital part of the marine ecosystem due to their productivity level, seagrasses provide food, habitat, and nursery areas for numerous vertebrate and invertebrate species. The vast biodiversity and sensitivity to changes in water quality inherent in seagrass communities makes seagrasses an important species to help determine the overall health of coastal ecosystems. Seagrasses perform numerous functions:

Stabilizing the sea bottom

Providing food and habitat for other marine organisms

Maintaining water quality

Supporting local economies
